• CCSS.Math.Content.5.NF.B.7aInterpret division of a unit fraction by a non-zero whole number, and compute such quotients.
  • For example, create a story context for (1/3) ÷ 4, and use a visual fraction model to show the quotient.
  • Use the relationship between multiplication and division to explain that (1/3) ÷ 4 = 1/12 because (1/12) × 4 = 1/3.

• CCSS.Math.Content.5.NF.B.7bInterpret division of a whole number by a unit fraction, and compute such quotients.
  • For example, create a story context for 4 ÷ (1/5), and use a visual fraction model to show the quotient.
  • Use the relationship between multiplication and division to explain that 4 ÷ (1/5) = 20 because 20 × (1/5) = 4.
